NOT FOR SALE OR DISTRIBUTION 2 CHAPTER 1 ■ Foundations of Epidemiology In recent years, the important role of epidemiology has become increasingly recognized. Epidemiology is a core subject required in public health and health education programs; it is a study that provides information about public health problems and the causes of those problems. This information is then used to improve the health and social conditions of people. Epidemiology has a population focus in that epidemiologic investigations are concerned with the collective health of the people in a community or population under study. In contrast, a clinician is concerned for the health of an individual. The clinician focuses on treating and caring for the patient, whereas the epidemiologist focuses on iden- tifying the source or exposure of disease, disability or death, the number of persons exposed, and the potential for further spread.

  • HIV and AIDS: a Module for Cnas and Hhas
    HIV AND AIDS: A Module for CNAs AND HHAs INTRODUCTION The human immunodeficiency virus (HIV) is a virus that is transmitted through sexual contact or contact with infected blood. HIV causes an illness called acquired immune deficiency syndrome - AIDS. AIDS was first diagnosed in New York City and San Francisco in 1981. However, there is evidence that HIV has actually been infecting people for many, many years before it was recognized and isolated cases of AIDS had occurred many years before the epidemic started. The cause of AIDS, HIV, was finally isolated in 1983. There are now over 33 million people in the world who are infected with HIV. A large number of them will develop AIDS, and AIDS is an enormous public health problem in the United States and worldwide. Modern medications have now allowed many people infected with HIV to avoid developing AIDS. However, there is no cure for HIV infection - the virus cannot be eliminated or eradicated - and there is still no vaccine available that can prevent the spread of HIV. Learning Break: Many people use the terms HIV and AIDS interchangeably, but it is important to remember that they are two different things. HIV is the virus that causes AIDS. AIDS is the disease - or group of diseases - that are caused by infection with HIV. Someone can be infected with HIV but not have AIDS. OBJECTIVES When the student has finished this module, he/she will be able to: 1. Identify a definition of HIV. 2. Identify a definition of AIDS. 3. Identify the basic defense mechanism the body uses against infections.

  • Botox® Reconstitution and Dilution Procedures
    BOTOX® RECONSTITUTION AND DILUTION PROCEDURES Indication Chronic Migraine BOTOX® (onabotulinumtoxinA)for injection is indicated for the prophylaxis of headaches in adult patients with chronic migraine (≥ 15 days per month with headache lasting 4 hours a day or longer). Important Limitations Safety and effectiveness have not been established for the prophylaxis of episodic migraine (14 headache days or fewer per month) in 7 placebo-controlled studies. IMPORTANT SAFETY INFORMATION, INCLUDING BOXED WARNING WARNING: DISTANT SPREAD OF TOXIN EFFECT Postmarketing reports indicate that the effects of BOTOX® and all botulinum toxin products may spread from the area of injection to produce symptoms consistent with botulinum toxin effects. These may include asthenia, generalized muscle weakness, diplopia, ptosis, dysphagia, dysphonia, dysarthria, urinary incontinence, and breathing difficulties. These symptoms have been reported hours to weeks after injection. Swallowing and breathing difficulties can be life threatening, and there have been reports of death. The risk of symptoms is probably greatest in children treated for spasticity, but symptoms can also occur in adults treated for spasticity and other conditions, particularly in those patients who have an underlying condition that would predispose them to these symptoms. In unapproved uses, including spasticity in children, and in approved indications, cases of spread of effect have been reported at doses comparable to those used to treat cervical dystonia and upper limb spasticity and at lower
